The controller includes a control member operable by a user, and a rotating body for rotating in one direction to wind a shifting cable and for rotating in another direction to unwind the shifting cable. A first transmission transmits movement of the control member into rotation of the rotating body at a first transmission ratio, and a second transmission transmits movement of the control member into rotation of the rotating body at a second transmission ratio. The second transmission ratio is greater than the first transmission ratio. A coupling mechanism is provided for allowing the control member to be selectively coupled to the first and second transmissions. |
